CHAPTER 4 FUNCTIONS

4.19 Peak Current Suppression Function
(2) Examples of dividing timing
(a) Four timing
The following table shows two examples.
The following shows the relationship between groups and the values (%) of CH Upper limit output limiter
(Un\G42, Un\G74, Un\G106, Un\G138).
In Example 2, the maximum number of groups is four; therefore, timing is divided into four timing. Because no
channel is set for Group 3, no channel starts transistor output at the timing for Group 3.
